POP and corrugated displays that warp
Display warp is a stand or a sign bowing after one face took ink, coating, or heat and the other did not. Moisture left unevenly, and the board curled.
Checks
- See which face is concave. The board curls toward the face that lost more moisture.
- Balance coverage. A flood on one side and nothing on the other is a curl waiting to happen.
- Store displays flat and wrapped until they go up. A warm shop dries the top sheet first.
- Check the board before you print. A sheet that arrived warped will not dry flat.
